Abstract (en)

[origin: EP3885111A1] A composite material forming method that reduces the occurrence of temperature unevenness in a composite material during heating is provided. The composite material forming method is a method for forming a composite material 10 including reinforcing fibers 12, and includes an equipotential-material connecting step and a magnetic-field applying step. The equipotential-material connecting step is a step of connecting end portions of the reinforcing fibers 12 with equipotential materials 16 to form an electroconductive loop including the reinforcing fibers 12 in the composite material 10 before reaction. The magnetic-field applying step is a step of applying a magnetic field 42 in a direction intersecting a plane formed by the electroconductive loop.
